Just got off the phone with Dayton of DPS-Motorsports and this new intake plenum replaces the restrictive factory "T" shaped plenum and replaces it with a "V" shaped plenum for improved flow. Dayton claims that with the stock ECU the Cayenne Turbo yielded 37 HP and with a ECU flash the truck should see over 40 HP! The Plenum costs $895. I was also told that if I didn't like the performance of the part that he would refund my money. It must really work. Does anyone have this on their Cayenne Turbo? I'm gonna order one and see what becomes of it... I Need more HP to close the distance on those sportscars...

 

hmmm... when i had mine , i have giac flash , and regular kn filters and bypass pipes and this is the dyno.. , that intake should yield more

 

Good stuff Alex. I noticed on your dyno sheet that you made 358 HP then 7 minutes later you made 423... What was going on? I have the exact same mods that you had so it's good to know where I might be in terms of HP. If this intake plenum yields 35-40HP this will be the steal of the century for $895... I need to install this part at the dyno to see what the difference is...
